Title: Picture signal processing device
Inventor: INOUE KEIICHI
IPC: H04N1/40
Filed: 1981-02-05
Abstract: PURPOSE:To clearly reproduce a fine black and white pattern, by detecting the fine black and white pattern from in an analog picture signal, and switching the fine black and white pattern part to a binary-coded digital signal for black and white binary recording, from a multi-value digital signal. CONSTITUTION:An analog signal from a terminal 15 is inputted to a discriminating circuit 11, a multi-value-coding circuit 12 and a binary-coding circuit 13, respectively. The multi-value-coding circuit 12 converts an analog picture signal to a digital signal of plural bits, and outputs it to a switching circuit 14. Also, the binary-coding circuit 13 converts the analog signal to a digital signal of 1 bit, and outputs it to the switching circuit 14. When a fine black and white pattern is detected by the discriminating circuit 11, the output signal of the binary-coding circuit 13 is converted to plural bits and is outputted from the switching circuit 14. In this state, when the fine pattern comes not to be detected by the discriminating circuit 11, the output signal of the multi-value-coding circuit 12 is outputted.

IPC: D06F79/02
Filed: 1989-01-26
Abstract: PURPOSE:To cause the regenerative amount of a base to correspond to an ironing time for informing accurately a user of a reheating time due to the temperature drop of the base by varying constitutionally the reheating time of the base during ironing with the base temperature and heating time. CONSTITUTION:When a temperature is set according to the kind of cloth and an iron body 1 is mounted on a mount 2, current is supplied to an exothermic body 3 to heat a base 4. When the temperature is set to iron 'cotton' for example, the temperature of the base 4 is maintained at 160 deg.C after it is heated to 160 deg.C. When the temperature of the base reaches '140 deg.C', a control circuit 37 lights a LED 11 to set 60-70secs. in a timer circuit 47. When the iron body 1 is removed, the control circuit 37 detects the removal on the basis of the output of an iron body detecting circuit 43 to start a counting action with the timer circuit 47. When the removal time exceeds 50secs., the LED 11 is turned off to cause reheating, and when the removal time exceeds 70secs., a buzzer circuit 46 is operated to cause again the reheating.

Filed: 1988-01-29
Abstract: PURPOSE:To reduce a spurious, which is generated in the output of a voltage control oscillator, by equipping a sample and hold circuit and removing a phase comparing frequency component to be included in the output of a loop amplifier. CONSTITUTION:Phase comparison between the output signal of a voltage control oscillator 1 and the output signal of a reference oscillator 2 is executed by a phase comparator 3 and the output signal of a pulse width, which is proportional to phase error quantity, is outputted.

Title: Image forming device
Inventor: OBA HIROYUKI
IPC: G03G15/20
Filed: 1996-01-08
Abstract: PROBLEM TO BE SOLVED: To prevent an image forming device from being soiled by the unfixed toner image of a recording material when the recording material is passed through a heat fixing device in the case that the recording material stopped on a carrying path is automatically ejected by heating the heat fixing device up to standby temperature before the recording material is carried and ejecting the recording material at an automatic paper ejecting speed being lower than the normal carrying speed of the recording material thereafter. SOLUTION: In the case that a paper is bitten by a nip part N when a main switch is turned on, electric power is supplied to a heater 3 before a main motor is started. While the electric power is supplied, the temperature of the heater 3 is monitored by the temperature thermistor 5 thereof until it arrives at the temperature for starting the main motor(standby temperature). The standby temperature is set to the sufficient temperature for fixing toner when the paper passes through the nip part N. Besides, when the temperature of the heater 3 arrives at a prescribed standby temperature, the main motor is started at the lower speed than the prescribed paper carrying speed for normally carrying the recording material P. Then, when the ejection of the material P is finished, an automatic paper ejection process is finished.
